The siblings have been in perfect harmony practically since birth. 

“My daughter noticed my son at 2 months, and at 3 months, they started holding hands every time they were near each other,” Sidibe detailed. “And so their bond started really, really quickly, which is really, really beautiful to watch.” 

Not to say the two are carbon copies. While they share a “goofy” personality, she noted, and love “high-fiving themselves in the mirror,” said Sidibe, “My son is like a chaotic cannonball, and my daughter is much more methodical. She stands up, she gets her balance, and then she takes a walk. But my son launches himself, like, dives everywhere.”

It’s a trait he may have picked up from Dad. 

Frankel, Sidibe recognized in her 2025 anniversary post, “has been running full speed towards me, everyday since we met in March of 2019 and if I had realized sooner what a wonderful husband he would turn out to be, I would’ve stood still and let him catch me sooner.”
